  • Method for optimizing CRT therapy
    Patent number: 8145306
    Abstract: A method to optimize CRT therapy using ventricular lead motion analysis, either radiographically or with three dimensional electromagnetic mapping, to determine whether focal dyssynchrony is present at baseline, and whether biventricular pacing improves synchronicity and fractional shortening, and if no improvement is evidenced, changing the timing offset, pacing configuration and/or repositioning the ventricular leads to optimize effectiveness of CRT therapy. Various uses of this method include: diagnostic, with temporary leads to determine presence or absence of dyssynchrony and response to pacing; and therapeutic, to guide lead placement and programming during implant of CRT, and to optimize reprogramming of CRT during follow-up.
    Type: Grant
